hazardous condition.
Please read this manual completely. It is important that you understand how the Electrode Steam works, and how
INTRODUCTION
to safely perform the required maintenance procedures. Read and understand all safety-related labels found on
and posted near the Electrode Steam. These labels provide additional instructions and important
safety information.
Safety Denitions
These safety terms identify information you must read.
CAUTION: Indicates a hazardous situation which, if not avoided, could cause bodily injury or
property damage.
WARNING: Indicates a hazardous situation which, if not avoided, could result in death or serious injury.
Safety Precautions
Make sure you read and understand the following safety hazards before installing, using, or working
with the Electrode Steam:
• Do not direct the steam nozzle at people.
• Water inside cylinder can be very hot. Read the warning label on the Electrode Steam and make sure
you understand the hazards of scalding hot water in the cylinder.
• Scalding danger from draining water. When the water tank empties, draining water can be hot enough
to cause injury. Make sure you know where the water exits the drain hose. Be certain hot water will not
pose a hazard to people or pets.
WARNING: Electrocution Hazard.
The Electrode Steam uses 120V or 240V, which can cause death or serious injury. Take precautions when
service is being preformed on the Electrode Steam or when removing the water tank or cover. If in doubt,
turn off the breaker which is operating the Electrode Steam and disconnect HVAC equipment power before
servicing.
CAUTION: Heavy Equipment and Water Hazard.
Improper installation or misuse can cause death, blindness, and water damage to home. Be sure you know
how to turn the Electrode Steam off, and how to drain the water tank safely.
CAUTION: Steam Condensation and Freezing Water Hazard.
Be sure the Electrode Steam Humidier is located in a conditioned space, as well as having proper
condensate and drain line locations. Improper installation can result in water damage to home.

Welcome!
Congratulations on your new humidier.
The Honeywell Electrode Steam humidier provides the high performance and efciency of steam, with easier
maintenance than traditional humidiers.
We are sure the Electrode Steam will be a welcome addition to your home.
• How is the Electrode Steam different from other humidiers?
- The steam goes directly into your hot air supply duct, rather than evaporating from a wet pad, which requires
furnace temperature to produce humidity efciently.
- The Electrode Steam delivers humidity independent of your furnace. This allows you to achieve ideal humidity
levels in your home, year-round.
- The Electrode Steam wastes less water than ow-through humidiers.
- The Electrode Steam operates automatically, just like a thermostat, to keep your home’s humidity at the
desired level.
- The Electrode Steam is easy to maintain. Just have your HVAC professional change the steam cylinder when
the unit determines its life is about to expire.
• What safety features does the Electrode Steam have?
- Separate sensors and water monitoring (via the electrodes and software) monitor water within the tank. These
two important components prevent the tank from being over-lled, running dry, and optimize steam production
with various water qualities.
- The auto-adaptive feature monitors the Electrode Steam humidier’s water supply, current, and load. The unit
also self-tests on a regular basis, letting you know when the unit should be serviced.
INTRODUCTION
• How should I get started? Your Electrode Steam must be installed by an HVAC Professional Installer. If the
Electrode Steam has just been installed, it should either be running and humidifying your home, or waiting for a
humidity call from the humidity control provided.
Once the Electrode Steam is up and running, all you have to do is use the humidity control to change the
humidity to your desired comfort.
Please read this manual completely for tips on getting the most out of your Electrode Steam.
Read your humidity control manual and make sure you know how to operate your system.
If you have questions, now or later, please ask your Installer or call Honeywell Customer Care
at 1-800-468-1502.

Steam Distribution
Steam generated by the humidier may be introduced into the air in several different ways. The most common
method for adding the steam into the air is to mount a steam distributor tube in a supply air duct.
Steam Line
The steam line between the cylinder steam outlet and the distributor serves two purposes: it is used as a conduit
to transfer the atmospheric steam from the humidier to the distributor, as well as providing a means to remove
condensate.
Condensate Return
Whenever steam is distributed condensate is formed in the distribution system. Insulating steam lines is one
important way to reduce the amount of condensate formed. Steam lines are sloped so that condensate does not
collect in the lines and create a restriction to steam ow. The condensate must be collected and removed from the
system so that it does not build up and leak into the duct. Condensate can be returned to the Electrode Steam ll

Which Electrode Steam model do I have?
The Electrode Steam is available in two sizes, each with a different humidifying capacity:
The Electrode Steam produces 11 gallons per day (GPD) when run on 120 V and 22 GPD when run on
240 V. It is generally suitable for homes 8,000 to 32,000 cubic feet in size.
The proper model for your home depends on many factors.
Size of the area to be humidied, ceiling height, window

date code of your Electrode Steam.
and insulation type, as well as your geographic area, all
affect how much humidity your
home needs.
Some activities in your home may create heavier loads for
the Electrode Steam. Vented replaces, high exhaust from
fans, or driers can reduce humidity in your home and make
the Electrode Steam work harder.

Sizing
IMPORTANT: The Electrode Steam should only be installed if it has been sized properly. Do not use square feet
when sizing a humidier installation. Instead, cubic feet must be used, since the humidity is lling a volume of
space (width x length x height). Also, take into consideration the “tightness” of a home’s construction.

What should I expect from my Electrode Steam?
Honeywell wants to make sure you know what to expect from your new Electrode Steam installation. Make sure
you discuss these items with your Professional Installer:
• Achieving Humidity Setpoint. It may take up to a week of continuous operation to initially achieve the

industry experts. You can adjust to your own comfort or until there is condensation on the windows. Lower the
setpoint if condensation appears.
humidity control may have a frost protection setting. See “What is a frost setting?” on page 10. The Cylinder
may also be at the end of its life, in which case you will be notied by the LED sequence.
• Setpoint Not Reached. If humidity doesn’t reach the setpoint, the Electrode Steam may be under-sized for the
home. This can be due to insulation, windows, arid climate, and other environmental factors. Also, the outdoor
temperature may be too low to maintain the humidity level.
• Home Ventilation. Excessive ventilation exhausts humidied air and replaces it with dry air. This can make it
hard to maintain the humidity setpoint. If you are installing a ventilator, use a solution that retains moisture. An
Energy Recovery Ventilator (ERV) is recommended.
• LED Status Lights. The HM700 user interface includes 2 LEDs that provide information about the humidier
status. Please see “What do the lights tell me?” on page 11 for more information.
• Water Draining. It is normal for the Electrode Steam to periodically drain some water automatically. This is
due to the humidier maintaining the perfect level of water conductivity and steam output.
• Water Conductivity. Your home’s water conductivity determines how quickly the Electrode Steam will produce
steam and also how often the replacement steam cylinder needs to be replaced.
• Energy Consumption. You may notice a slight increase in overall energy consumption when operating
any humidier. However, the Electrode Steam will make the home feel warmer. This allows you to lower the
temperature setting on the thermostat. Every degree lower on the thermostat can save up to 3% on heating
costs.

How do I operate the Electrode Steam?
Once the Electrode Steam is installed and running, operation is automatic. Use the humidity control provided to
make any changes to the setpoint, or to turn the Electrode Steam on or off.
Your Professional Installer congured the Electrode Steam so that it only creates steam when conditions in your
HVAC system are right. Steam can only be produced when your system fan is blowing air through the duct.
Ask your Professional Installer if you have questions about how to operate the Electrode Steam.
• How do I use the humidity control? Whenever humidity in the home is lower than the humidity control’s
setpoint, the control will call for humidity. Some controls will also monitor outdoor conditions to ensure indoor
humidity does not condense on windows and walls. Refer to the manual provided with your humidity control for
instructions on setting the control. There are two different types of humidity control:
Thermostat with integrated humidity
control (such as Prestige IAQ, VisionPRO
8000, or Lyric).
Humidity control separate from the thermostat

• What should my humidity setpoint be? The outdoor air temperature affects how much humidity can be
retained by the air in your home. Use this table as a starting point. Then adjust the humidity control to your own
comfort or until condensation appears on the windows.
Outdoor Recommended Relative
Temperature Humidity Setting
-20°F (-29°C) 15%
-10°F (-23°C) 20%
0°F (-18°C) 25%
10°F (-12°C) 30%
20°F (-7°C) 35%
>20°F (-1°C) 35%
• What is a frost setting? Some humidity controls (such as Prestige, VisionPRO 8000, and HumidiPRO)
contain a Window Frost Protection feature which limits humidity output based on outdoor conditions. For
example, on colder days, the air in your home can hold less humidity. The humidity control automatically lowers
the humidity setpoint accordingly, to prevent frost from appearing on the inside of your windows.
OPERATION
Lower the frost setting by one value each morning that you see frost or condensation on windows. Allow 24
hours for the new setting to take effect before re-adjusting. Once you have this set to a comfortable level
without condensation, you will not need to adjust further. You can adjust your humidity setpoint without
worrying about condensation.
MCR2798
Manual humidity controls do not have built-in frost settings. They require you to adjust the humidity setpoint
when the outdoor temperature changes. Use higher humidity setpoints when the temperature is warmer, and
lower setpoints when the temperature is cooler.

What should I do at the end of the season?
The Electrode Steam automatically shuts down when humidity is not needed for an extended period. After several
days of inactivity, the water tank will drain and remain empty until humidity is called again. This prevents water
from stagnating inside the tank. The Electrode Steam will rell the tank with water and reset itself when your
control calls for humidity again.
• What if I go on vacation? Even though the Electrode Steam’s water tank will drain automatically after several
days, Honeywell recommends shutting off the Electrode Steam water supply and turning off the humidity
control for extended leaves. Upon return, turn on the water supply and reset the control to the desired setpoint.
What should I do if the LED light is blinking, or if something is
wrong?
The lights will blink when the internal dignostics systems needs attention. See LED list on page 11.
